Why I cannot note this?
It seems to me, that it's still needed to try to catch 4 pixels, not 10 or
wider?..

  "invisible" region around each non-maximized window about 4px thick
  that can be used for resizing (in addition to the visible border). Or
  perhaps there should be a border thickness option on the System >

Yes. 
And MKV-files is stopped to fiil.

I tried 30, 25, 20, 15 fps -- the same result: when MVK-files reeaces 2
GB, guvcview hangs up...

I doubt, that AVI is better... :-)

Yes.  30, 25, 20, 15 fps... 960, 800, 640 pixels...  [On a Core i5
processor.]

> You should also test with different codecs and with the avi muxer,

Yes, tried MPEG2, H264... The same... 2 GB... (on any FS: ntfs, ext3...)

difference.

I will try without audio... 
Thank you.
